Not much you could do. You left the lab on an unhappy term. This has nothing to do with whether the boss is Jewish or Chinese. I am not sure that there is much you could argue for. Your best bet is to work with him professionally to get those unpublished results out and hopefully he recognize your contribution.
Sounds like you quit the lab? If that's the case, you quit the projects as well :) Your boss thinks your contribution is not enough and there is ethics issue as well by quiting a project? I am not sure that any suggestions above apply because you seem to be on a shaky ground.
